Caladium macrotites Schott

• Genus: Caladium
• Botanical Background: Described by the botanist Schott, Caladium macrotites adds to the rich legacy of botanical exploration in tropical aroids. Its naming reflects historical research into the natural diversity of the group.

• Geographical Range: Native to tropical rainforest regions of South America where dense vegetation and warm climates prevail.
• Environment: Thrives in humid, warm conditions with rich, well-draining soils; grows best in shaded forest understories with consistent moisture and moderate light.

Leaves

• Large and striking
• Smooth textures and prominent venation
• Coloration and size make them a standout feature in ornamental collections

Inflorescence (Spadix & Spathe)

• Slender spadix and a surrounding spathe
• Flowers are modest in appearance
• Primarily serve to attract insect pollinators

Growth Habit

• Terrestrial species grows from a tuberous rhizome
•  Forms clumps over time
• Suitable for both container gardening and landscaped tropical gardens

Light Requirements

• Bright and indirect light
• Direct sunlight may scorch the leaves, while too little light can reduce the vibrancy of its coloration

Watering & Humidity

• Regular watering is essential to keep the soil consistently moist
• High humidity levels similar to those in tropical rainforests are beneficial for its growth

Soil & Potting Mix

• A rich, well-draining potting mix with added organic matter is recommended
• Containers should have adequate drainage to prevent water retention and root rot

Temperature & Fertilizer

• Ideal temperatures range from 65°F to 85°F
• Balanced fertilizer applied during the growing season helps maintain vigorous foliage and overall plant health

Division and Cuttings

• Most common method of propagation is through rhizome division
• Dividing the plant during repotting ensures that each new section contains an active growing point

Seeds

• Less common due to variable germination rates and a longer maturation period compared to vegetative propagation

Typical Issues

• Spider mites and mealybugs
• Fungal root rot may occur if the soil remains too wet

Treatment Recommendations

• Organic insecticidal treatments such as neem oils
• Ensuring proper watering and drainage are effective ways to manage pests and prevent fungal issues

• Impressive leaf size and bold venation have made it a subject of interest among botanists and tropical plant collectors
• Large foliage often inspires tropical garden designs

• Oversized leaves and its ability to serve as a focal point in both indoor plant collections and outdoor tropical landscapes

Wild Population Status

• No major conservation concerns currently reported
• Protecting tropical rainforest habitats is essential for the long-term survival of many aroids

Market Availability

• Considered somewhat rare in commercial cultivation, adding to its appeal among dedicated collectors and enthusiasts
